Gamma and beta frequency oscillations in response to novel auditory stimuli: A comparison of human electroencephalogram (EEG) data with in vitro models

Investigations using hippocampal slices maintained in vitro have demonstrated that bursts of oscillatory field potentials in the gamma frequency range (30-80 Hz) are followed by a slower oscillation in the beta 1 range (12-20 Hz). In this study, we demonstrate that a comparable gamma-to-beta transition is seen in the human electroencephalogram (EEG) in response to novel auditory stimuli. Correlations between gamma and beta 1 activity revealed a high degree of interdependence of synchronized oscillations in these bands in the human EEG. Evoked (stimulus-locked) gamma oscillations preceded beta 1 oscillations in response to novel stimuli, suggesting that this may be analogous to the gamma-to-beta shift observed in vitro. Beta 1 oscillations were the earliest discriminatory responses to show enhancement to novel stimuli, preceding changes in the broad-band event-related potential (mismatch negativity). Later peaks of induced beta activity over the parietal cortex were always accompanied by an underlying gamma frequency oscillation as seen in vitro. A further analogy between in vitro and human recordings was that both gamma and beta oscillations habituated markedly after the initial novel stimulus presentation

Talijansko kazalište u 17.stoljeću s naglaskom na operu i operne kostime

Okosnica ovog rada su zbivanja u kazališnoj umjetnosti 17.stoljeća na području Italije. Rad daje pregled važnijih povijesnih okolnosti koje su oblikovale umjetnost baroka te samim time uvjetovale rođenje opere koja je ubrzo postala esencija kulturnog i društvenog života Europe. Cilj je razdvojiti i analizirati komponente kazališne umjetnosti s fokusom interesa na kazališnom kostimu. Rad je protkan velikim imenima koja su obilježila povijest glazbe, no ponajviše onima koji su pridonijeli realizaciji vizualnih komponenti kao što su kostimi i scena, a bez kojih barokna opera ne bi bila ono što je danas, sinonim za nenadmašivu audio-vizualnu raskoš

Nearly all Power to Imagination

V diplomové práci se věnuji interpretaci a analýze imaginativních obrazů, které jsou základem metodiky některých pedagogů zpěvu. Konkrétněji analyzuji představy, jež ve svých hodinách zpěvu na DAMU používá Šárka Malínková. (Nejen) na DAMU je pedagogická praxe při výuce zpěvu založena na metodách imaginace, za pomocí kterých student/ka dosahuje požadovaného tónu, výrazu a emoce. Využití imaginace při výuce zpěvu je běžnou a tradičně používanou metodou, nicméně se často dostává do střetu s exaktním jazykem, který pro své závěry volí vědecká sféra. Hlavními východisky teoretické části jsou poznatky o zpěvu a zpěvním hlase, ohledání pojmu představivost a nastínění debaty, která v této oblasti probíhá. Výzkumná část je založena na analýze pěveckých cvičení, které Malínková se svými studenty/kami praktikuje. Cílem práce pojmenování univerzálních atributů užívaných obrazů a snaha o nalezení průsečíku mezi představou a tělesným projevem. V neposlední řadě je cílem práce zapojení do debaty mezi vědeckým a nevědeckým jazykem pomocí vlastní zkušenosti

Twenty years of efficiency research in Czech and Slovak banking – A bibliometric analysis

The article is a survey of 44 empirical studies that applied frontier techniques in analyzing efficiency of Czech and Slovak commercial banks in a hope to summarize the state of the art of efficiency research in Czech and Slovak banking. A sample of 44 journal articles was extracted from the Web of Science™ database, and a bibliometric analysis was conducted to identify the most active authors and most influential works to establish mutual relationships between them and to sketch the main research trajectories. The paper contributes to the extant literature by providing guidance for new researchers and identifying for efficiency research on Czech and Slovak banking: (i) the most productive authors as well as the works with the most impact; (ii) the network structure amongst the authors and works; and (iii) main paths of knowledge diffusion across the surveyed works. The findings indicate that efficiency research of Czech and Slovak banks grew out of global banking efficiency research and is thus its integral part. Lotka’s law applied to Czecho-Slovak banking efficiency research does not suggest that its productivity patterns are altogether different from its global counterpart. The first identifiable wave of research was represented by foreign authors who examined issues of economic transition and its impact on the performance of banks. This wave of research endured until about 2013, when the torch passed into the hands of authors of domestic provenience. The findings are useful in bridging the gap between the accumulated knowledge in the field and the new research directions

Advent of English Communication Skills in India and Its Impact on Employability

The paper highlights the advent of the English language into the Indian sub-continent during various decades of the 20th century. The momentum of English usage has increased since the 1970s. The paper reiterates that many Commissions have advocated for Project- Method and Activity- Method to teach communication skills in English. It further reinforces that English is truly considered global and transcends the boundaries. Thereby, making the English learners not local citizens but global citizens. English is widely recognized as the world's lingua franca since it unites all peoples of the world linguistically and serves as the main medium of communication for trade, aviation, entertainment, and diplomacy as well as for scientific and technological activities. The incredible increase of graduates, post graduates and doctoral degree holders in various disciplines such as engineering, medicine, arts, science, humanities and management, has further brought forth challenges and competitions in the global market, and this has, however, posed a threat to the job seekers, who lack communicative competence in English. The majority of the top national and international businesses, organizations, and academic institutions communicate in English for a variety of reasons, and the majority of online resources are in English

LIFE TABLES OF LEPIDOSAPHES ULMI (L.) AND PALAEOLECANIUM BITUBERCULATUM (TARGIONI TOZZETTI) (HEMIPTERA: COCCOIDEA) ON APPLE TREES IN VAN PROVINCE, TURKEY

LIFE TABLES OF LEPIDOSAPHES ULMI (L.) AND PALAEOLECANIUM BITUBERCULATUM (TARGIONI TOZZETTI) (HEMIPTERA: COCCOIDEA) ON APPLE TREES IN VAN PROVINCE, TURKEY. Apples are the most important cultivated crop in Van Province in Eastern Anatolia Region, Turkey, where Lepidosaphes ulmi (L.) and Palaeolecanium bituberculatum (Targioni Tozzetti) (Hemiptera: Coccoidea) are amongst the most economically important pest species. Life-table data were collected in the field for these two species in two different apple orchards. The development time for each stage was recorded once a month in the Winter and every fortnight during the Spring, Summer and Autumn. In each orchard, both shoots and leaves of five randomly selected trees were sampled and each stage of the two scale species was counted. The life-table data were analyzed with regard to the age of the insects and the season, and it was found that L. ulmi and P. bituberculatum had one generation a year. Of several mortality factors, parasitisation was the most important (25.8% for L. ulmi and 23.8% for P. bituberculatum). Key words: Aphytis mytilaspidis, aphelinid, Coccophagus palaeolecanii
